State-of-the-art vacuum gauges for laboratory and industrial operation have to meet high standards in terms of gauge head resistance to chemicals, reliability in rugged applications and operator-friendly interfaces. VACUUBRAND has a comprehensive range of electronic measuring instruments for the range of atmospheric pressure to 5 × 10-9 mbar.

• A lot of applications in the laboratory call for electronic vacuum regulation, that is, constantly adapting the pump's volume flow rate to process requirements. The maximum volume flow rate of the unregulated pump can be changed in various ways:
• by cyclically turning the pump on/off (with the VNC 2 controller or the CVC 3000 controller with module VMS-B)
• by cyclically opening/closing an in-line solenoid valve (CVC 3000 or VNC 2) or
• by changing the pump´s motor speed continuously (VARIO® pumps in connection with CVC 3000 or VNC 2 VARIO

The DCP 3000 is an outstanding vacuum gauge with large illuminated display. The brand new VSP 3000 vacuum sensor is based on thermal conductivity (Pirani) and offers a wide measurement range from atmospheric pressure down to 10-3 mbar. The wetted parts are made of chemically resistant plastics and alumina ceramics. It features a much better chemical resistance and ruggedness than conventional Pirani sensors with their fragile metallic spiral-wound filament.

The DVR 2 has an integrated vacuum sensor made of alumina ceramic with outstanding corrosion resistance and superior long-term stability. A particular advantage is its cordless, battery-powered operation.

The CVC 3000 manages vacuum processes by controlling vacuum pumps, vacuum and coolant valves and accessories. The illuminated graphical display with clear text menus and the jog wheel make its handling nearly self-explanatory. Depending on its version a ceramic diaphragm vacuum sensor and venting valve are already integrated (or externally connectable). The ceramic vacuum sensor is chemically highly resistant, measures gas-type independent and accurate Ten fully configurable programs (with up to ten time and pressure steps each with control functions such as venting, pumping or automatic evaporation) can be easily edited and stored. External valves and sensors for liquid level and vacuum down to the fine vacuum range (VSK 3000 and VSP 3000) connect simply and are recognized automatically via the VACUU·BUS® control system. Valves with electromagnetic (solenoid) drive are used for operating cycles with short intervals and, therefore, are often used as vacuum control valves. The straightforward design provides a valve with low leakage rate. The valves in version VV C are made of materials with excellent chemical resistance. The sealing material of the VV-B 6C is a chemically highly resistant fluoroelastomer with better form stability than common PTFE, and with excellent long-term leak tightness characteristics.

Compact vacuum controller with vacuum valve and sensor – ready to use.
The CVC 3000 detect is a compact two-point vacuum controller. With its integrated ceramics membrane vacuum sensor and ventilation valve, its "detect" control function is a particularly convincing feature: It allows for automatic determination of the boiling pressure, which significantly simplifies working with solvent evaporation. The integrated check valve and the chemicals vacuum valve make it a compact, easy to install unit for vacuum regulation. Its electronic control significantly increases the process efficiency of your existing vacuum pumps or networks; you can recover more solvent which helps to protect the environment. The programmable CVC 3000 detect is available as a tabletop unit as well as for mounting on a stand.
